London Irish head coach Brian Smith paid tribute to Halani Aulika after the powerhouse prop continued his try-scoring run with a double in the Exiles' 47-28 Aviva Premiership win over London Welsh.

Aulika now has scored 11 tries in all competitions this season and his brace was part of a seven-try riot for Irish against a Welsh side already guaranteed to finish bottom of the table.

"I'm delighted for him," Smith said. "I think the whole team wanted him to stay on to get a hat-trick. For a tighthead to get a hat-trick, you wouldn't have seen that every day."

He added: "Once you get into the opposition 22 he is a real strike-force. He knows his way to the try-line.

"I think he is clearly the best short-range try scorer in the league, and there's a lot of him.

"The game was a good one for the neutral. Both teams wanted to play.

"We were running from our own try-line and they did too. There are things we are happy about as well as things we are not. Coaches are never happy, but it was a pretty good day all round."

London Welsh chief Lyn Jones called on his side to show some more commitment in their final Premiership clash of the season despite their lowly league position.

"Some things that have been good for us this year have been our attitude and line speed, but that disappeared out there," he said.

"We allowed them to bring their wingers into the game. I thought they were very good and influenced the game. We didn't control that at all. You need to be motivated and that's the key going into the last game. That can't come from me it has to come from that group."
